Patented Aug. 7, 1906 Application filed December 5. 1905- Serial No. 290,479.

To all whom it may concern:

Be it known that I ANDREW J. FOUCHER, a citizen of the United States, reslding at Hope, in the county of Kootenai'and State of Idaho, have invented certain new and useful Improvements in Boom-Chain Couplin s; and I declare the following to e a full, clear, and exact descriptlon of the invention, such as will enable others skilled in the art to it appertains to make and use the same.

This invention relates to an improved coupling for booming-chains and the like, and has for its object the production of a device of this character the coupling members of which are readil connected and disconnected when desired: but are, held in coupled relation against accidental disconnection.

The nature of. the invention will be readil understood, reference being had to the i0 lowing detailed description and to the accompanying drawings, in,wh1ch Figure 1 is a perspective view of the coup ling, the partsbeingin connected and locked condition. Fig. 2 is a side elevation showing the arts in uncoupled condition. Fig. 3 is a horizontal sectional view.

1 Referringto the drawings by numerals, v1 designates the main body of the coupling of rectangular cross-section and provided at one end with'a headed pin 2 for connection a swivel-eye 3, to which an end of the chain or the like is attached. Theother end of said body is at an angle to the latter and is bifurcated to provide ears 4, between which is arranged the pivoted end of a hook 5, apin 6 passing through the ears and hook end serving as the pivot on which the hook may swing. 1

y The free end 7 of the hook is adapted in coupling position to rest in a shallow recess in t e top of the body 1, in which position it confines a link 8, having swivel connection with an eye 9 for attachment with the other end of'the chain or the like.

10 is a sleeve slidable on the body to confine and release the free end 7 of the hook. Fig. 1 shows the sleeve in confining position, and in Fig. 2 the sleeve is shown in releasing position to permit the hook to swing open and free the link and eye and chain end. To -lo'ck'the sleeve in confining position, I employ two spring-catches 11 12, fastened by a pin or pins 13 in recesses 14 in the sides of the body 1. Each catch has at its free end a lockin -shoulder 1'5 normally projecting beyond t e side of the body to engage the end .of the sleeve when the latter is in co g position, as shown in Fig. 1. The sleeve is thus locked against accidental uncoupling movement at two points, but isreadily unlocked by hand by pressing the free'ends, of the catches inwardly. The catch-shoulders have beveled approaches whereby the catches are forced inwardly in the coupling movement of the sleeve. As the sleeve passes the shoulders the free ends of-the catches move outwardly by spring action, as Wlli be understood.

I claim as my invention-e 1. A coupling for boom-chains and the like, comprlsin a body, a hook pivoted thereto and adapt'e to bear in its closed'posltion against said body, a sleeve vslidable on the bod to confine and release the free end of the ook, and a spring-catch for locking the sleeve in its confining position.

2. A couplingfor boom-chains and the like, comprisin a body, a hook pivoted thereto and adapte to bear in its closed position against said body, a sleeve slidable on the body to confine and release the free end of the hook, and a spring-catch at each side of said body for locking the slee've in its confining position.
